Figure 9.

The eosin and hematoxylin dye absorption spectra and the average spectral error of the eosinophils; the spectral error of the eosinophils is scaled to have a clearer illustration. We can observe that the error peaks of the eosinophils correspond to the absorption peak of the hematoxylin dye. This could imply that the difference between eosinophils and other tissue structures which are stained similarly lies on their absorption of the hematoxylin dye.
